Yeah I thought the 5" was closer to 10psi.

FWIW I was making 13psi at redline with the 4.5" pulley.

How does the car feel at WOT? Fast as hell? My car was only making 550 according to the Shop's dyno and it felt pretty quick.

Yeah, on 100 octane and that 93 octane tune the best i made was 612 / 480 with Lund tuning. Can't seem to get past that for some reason even with more timing. Tried a different dyno, similar results. I haven't hit 500 torque even though I should be closer to 550. I don't know why mine won't do more, I don't think my inlet is collapsing because it makes 11-12 psi with the D1SC but... Hell who knows.

That's what pulley was shipped with mine. I asked for it though.

Stage 2 dedicated 8 rib crank pulley is supposed to be 8". That with a 5" blower pulley on the calculator says 10.22. On a mechanical boost gauge and the dyno boost monitor it hit 11.4 on the 93 octane tune and 11.9 on the race tune on multiple pulls. I have no idea why. Could it be a restriction for the hose between the intercooler and the throttle body? The hose that goes directly to the throttle body has a pretty tight bend to it, but I think the boost is measured in the manifold right?

Once the car is about 3500 to 4000 rpm, I can feel the power start to build, and it feels pretty fast up real high. It doesn't feel a whole lot different below 3000 or even 3500 under most driving. I wonder if I have a restriction somewhere, but I can't think where. If it's making boost it shouldn't be an issue right?

I would think if there was a restriction, it would make more boost. Maybe? No? Take it to the track and see what it does. Is it an auto?

Stick. Ran 12.6 at 124 on blower on stock tires, spun most of eighth mile before fully hooking up right

Time for some tires. Lol. Decent mph.

I'm debating on swapping to the 4.13 pulley, but I doubt my BAP can keep up on E85.

You are running stock pump, ID1000, and Bap on E85?

Yes. 22v JMS

Yes. 22v JMS

Hmmm... are you able to check your fuel pressure to see what its at? My tuner will not tune E85 unless I change pump. I have same fueling setup as you, minus the E85. I am running 93 and torco. Nice to know it will support that power with stock pump.

Lund is partially right and partially wrong. the 22v JMS will hold about 800-850whp on E85 with ID1000s and maintain AF. Pressure does drop, but thats an issue with returnless fuel.
